Maven+mybatis教程

首先，配置maven

在eclipse中把maven路径和settings.xml文件配置好之后，否则后续会有一些问题

可以设一个环境变量M2_HOME指向你的maven安装目录

M2_HOME=G:\java\apache-maven-3.3.3

然后在Window->Preference->Java->Installed JREs->Edit

在Default VM arguments中设置

-Dmaven.multiModuleProjectDirectory=$M2_HOME



新建mavenproject 直接默认下一步。

pom.xml文件如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration> <classPathEntry location="D:\java\mybatis\mybatis-generator-core-1.3.2\lib\mysql-connector-java-5.1.18-bin.jar" /> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true" /> <property name="suppressAllComments" value="true" /> </commentGenerator> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/test" userId="root" password="123456"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <javaModelGenerator targetPackage="test.upload.model" targetProject="src\main\java"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <sqlMapGenerator targetPackage="test.upload.mapping" targetProject="src\main\java"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <javaClientGenerator type="XMLMAPPER" targetPackage="test.upload.dao" targetProject="src\main\java"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <table tableName="user" domainObjectName="User" enableCountByExample="true" enableUpdateByExample="true" enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="true"></table> </context></generatorConfiguration>这个generatorConfig.xml可以放到src\main\resources目录中。如果没有这个文件夹，就新建一个。这样，这个资源文件会被mybatis generator找到并解析。

然后就用maven来产生代码。右键点你的项目，选择Run as->Run configurations，出来对话框如图：



输入对了以后就点Run了。后面就是一些maven的log了，可以看到产生了很多代码。

看到这些表示成功了
